I seem to remember DD11 having this issue the first time she took it. Kids in AL take it every year with other standardized tests. The first time she took it she really overthought a lot of questions and had trouble finishing and it caused her score to be low (for her). Last year, however, she came home after taking it and said she "got it", meaning she understood what to do with the questions. She was right because her score was enough to get her into the gifted program after previously being denied services (they don't accept outside testing).

I am in no way an expert, but the OLSAT seems to be a strange animal. DD learned from experience how to take the test, I guess. IMO, that makes it a less reliable instrument.
